Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an opening / closing member control device and an opening / closing member control method for controlling an opening / closing operation of an opening / closing member such as a roof glass, a window glass, a sliding door of an automobile.

[0002]

2. Description of the Related Art Conventionally, some sunroof devices mounted on automobiles are provided with an automatic opening / closing switch in addition to a normal opening / closing switch for sliding and opening the roof glass only during operation. Once the auto slide open switch is operated, no further operation is required,
In addition to the automatic slide opening operation that slides the roof glass from the fully closed position to the fully open position all at once,
Once the auto slide close switch is operated,
The roof glass is configured to perform an automatic slide closing operation in which the roof glass slides from the fully open position to the fully closed position at once. A sunroof device that performs such an automatic opening / closing operation generally has a function of detecting a pinch when a foreign object is trapped during the automatic slide closing operation of the roof glass and reversing the roof glass in the fully opening direction. .

A sunroof device having such a function is usually equipped with a rotation detection device for detecting the rotation direction and rotation cycle of the drive motor. The device is configured, for example, in the same manner as the technique disclosed in Japanese Patent Laid-Open No. 5-180665, and is arranged to output output signals (pulse signals) having different phases based on the rotation of the drive motor. It has a pair of rotation sensors. The device detects the rotation cycle of the drive motor based on the output signal (pulse signal) output from the rotation sensor, and utilizes the phase difference of the output signal (pulse signal) output from each rotation sensor. The rotation direction of the drive motor is detected. Then, the sunroof device counts the rotation cycle of the drive motor and detects the open / closed position of the roof glass by adding the counted number in the opening direction and subtracting the counted number in the closing direction, and also detects the rotation direction of the driving motor. Detects the opening / closing direction of the roof glass.

That is, in the sunroof device, in the normal opening / closing operation by the operation of the normal opening / closing switch and the automatic opening / closing operation by the operation of the automatic opening / closing switch, the count number is added or subtracted based on the operation of the opening / closing switch to open / close the roof glass. Is detected, the power supply to the drive motor is stopped at the fully open position or the fully closed position to stop the operation of the roof glass. Also, if a pinch occurs during the automatic closing operation, the drive motor is rotated in reverse to reverse the roof glass by a predetermined amount, and based on the reverse rotation of the drive motor, the count number is switched from subtraction to addition to open / close the roof glass. It is designed to detect the position.

[0005]

If one rotation sensor fails for some reason, the rotation cycle of the drive motor can be detected only by the other normal rotation sensor, but two output signals (pulse signal The direction of rotation of the drive motor, which is detected by the phase difference of), cannot be detected. Therefore, in the above configuration, when a trapping occurs during the automatic closing operation and the roof glass reverses, the rotation direction of the drive motor changes in the middle, but the rotation direction cannot be detected. Cannot be switched to, and the deviation between the opening / closing position of the roof glass and the actual opening / closing position of the roof glass based on the count number becomes large. Therefore, when the roof glass is opened / closed next time, the roof glass cannot be normally opened / closed.

Therefore, the conventional sunroof device has the same structure as the power window device disclosed in Japanese Patent Laid-Open No. 7-109868, and when the rotation sensor fails, either the normal open / close switch or the automatic open / close switch is operated. However, based on the operation, the driving of the drive motor is permitted for a predetermined time to open and close the roof glass.
That is, in the conventional sunroof device, the counting operation is invalidated to prevent the malfunction of the device.

However, if only one of the rotation sensors fails, the rotation direction of the drive motor cannot be detected, but the rotation cycle of the drive motor can be detected. That is,
Although the normal opening / closing operation can be performed by operating the normal opening / closing switch, and the automatic opening / closing operation by the operation of the automatic opening / closing switch can also be normally performed before the trapping occurs, the roof has the above configuration. The operation is troublesome because it is necessary to repeatedly operate the open / close switch in order to operate the glass to an arbitrary open / close position of the operator, such as a fully closed position or a fully open position.

The present invention has been made to solve the above problems, and an object thereof is to detect the rotation cycle and the rotation direction of a drive motor by a pair of rotation sensors to detect the opening / closing position and opening / closing of the opening / closing member. An opening / closing member control device and an opening / closing member control method for detecting a direction, wherein even if an abnormality occurs in an output signal from one rotation sensor, the opening / closing member is opened / closed by operating the opening / closing switch once while preventing malfunction of the device. An opening / closing member control device and an opening / closing member control method capable of opening / closing a member to an arbitrary opening / closing position of an operator.

And an entrapment control means for detecting the entrapment by the opening and closing member when the opening and closing member is in the automatic closing operation and detecting the entrapment to reversely drive the drive motor to release the entrapment. In the member control device, when one of the output signals from the rotation sensor is abnormal, the command signal from the automatic closing switch is invalidated, and a prohibition control means for prohibiting the automatic closing operation of the opening / closing member is provided.

According to a second aspect of the present invention, a drive motor that opens and closes an opening and closing member that is arranged so as to be reciprocally slidable, and a command signal that normally opens and closes the opening and closing member during operation are output. A normal opening / closing switch, an automatic opening / closing switch that outputs a command signal for automatically opening / closing to a predetermined position without any subsequent operation once operated, and a repeating cycle corresponding to the rotation of the drive motor and a predetermined mutual opening / closing switch. A pair of rotation sensors each outputting an output signal having a phase difference, and detecting the rotation cycle of the drive motor based on the cycle of the output signal output from each rotation sensor to detect the opening / closing position of the opening / closing member. , Detecting the rotation direction of the drive motor based on the phase difference of the output signal to detect the opening and closing direction of the opening and closing member, The drive motor is controlled based on the command signal from the switch and the detected opening / closing position and opening / closing direction of the opening / closing member, and when the opening / closing member is in the automatic closing operation, the pinching by the opening / closing member is detected, and the pinching is performed. In the opening / closing member control device including a control unit that reversely drives the drive motor to release the pinching, when the control unit has an abnormality in one of the output signals from the rotation sensor, The command signal from the automatic closing switch is invalidated, and the automatic closing operation of the opening / closing member is prohibited.

According to a third aspect of the present invention, in the opening / closing member control device according to the second aspect, the drive motor, the rotation sensor, and the control means are integrally configured as a drive unit.

According to a fourth aspect of the present invention, an opening / closing member arranged so as to be reciprocally slidably movable is opened / closed by a drive motor, has a repetition period corresponding to the rotation of the drive motor, and has a predetermined phase difference from each other. An output signal having each is output from a pair of rotation sensors, the rotation cycle of the drive motor is detected based on the cycle of the output signal output from each rotation sensor to detect the open / close position of the opening / closing member, and the output A normal opening / closing switch for normally opening / closing the opening / closing member while detecting the opening / closing direction of the opening / closing member by detecting the rotation direction of the drive motor based on the phase difference of the signal, and the subsequent operation once operated.

The command signal from the automatic closing switch is invalidated, and the automatic closing operation of the opening / closing member is prohibited. That is, when one of the output signals from the rotation sensor is abnormal, the rotation direction of the drive motor cannot be detected. Therefore, if a pinch occurs during the automatic closing operation, the drive motor is driven in reverse without operating the open / close switch, so the open / close position of the open / close member detected based on the output signal of the rotation sensor and the actual open / close position of the open / close member. The difference between the two becomes large and it interferes with the subsequent opening and closing operations. Therefore, by prohibiting the automatic closing operation, malfunction of the opening / closing member control device can be prevented. Further, in this case, since the operation of the opening / closing member by the normal opening / closing operation can be continued at least, the opening / closing member can be opened / closed to any opening / closing position of the operator by one operation of the normal opening / closing switch.

According to the third aspect of the invention, the drive motor, the rotation sensor and the control means constituting the opening / closing member control device are integrally formed as a drive unit, so that the assembling work of the device is facilitated. be able to.

BEST MODE FOR CARRYING OUT THE INVENTION An embodiment of the present invention will be described below with reference to the drawings. FIG. 3 is a perspective view of a main part of an automobile equipped with a sunroof device, in which a roof glass 4 as an opening / closing member is provided for a skylight 3 formed on a roof panel 2 of the automobile 1. Roof glass 4
Is provided so as to be reciprocally slidable in the front-rear direction and vertically movable around the vehicle width direction as a fulcrum at its front end portion. That is, the roof glass 4 is provided so as to perform a slide opening / closing operation and a tilt opening / closing operation. Then, the roof glass 4 is subjected to a slide opening / closing operation and a tilt opening / closing operation via a drive transmission mechanism (not shown) based on the drive of the drive motor 5 shown by the broken line in FIG. The drive motor 5 constitutes a drive unit 10 together with a drive control circuit 11 described later for controlling the drive of the motor 5,
The drive unit 10 is disposed between the roof panel 2 in front of the skylight 3 and a molded ceiling panel (not shown) on the indoor side.

FIG. 1 is an electric block diagram for explaining the electrical structure of a sunroof device for driving and controlling the drive motor 5. Drive control circuit 1 for driving and controlling the drive motor 5
1 is connected to a battery (not shown), and the circuit 11 is supplied with drive power + B from the battery. Drive power supply + B
Is adjusted to a predetermined power supply voltage by the power supply circuit 12 in the drive control circuit 11 and supplied to the control unit 13 as the detection unit, the opening / closing control unit, the pinch control unit, the inhibition control unit, and the control unit.

The drive control circuit 11 is connected to an ignition switch SW1. Ignition switch SW
1 is connected to the control unit 13 via the input circuit 14 in the drive control circuit 11. Ignition switch S
When W1 is operated, it outputs an operation signal (ON signal) to the control unit 13 via the input circuit 14. The control unit 13 operates based on the drive power supplied from the power supply circuit 12 based on the ON signal of the ignition switch SW1.

Further, the drive control circuit 11 has various switches SW2 to SW for opening and closing the roof glass 4.
7, that is, the normal slide opening switch SW2, the normal slide closing switch SW3, the automatic slide opening switch SW4,
Auto slide close switch SW5, tilt open switch S
W6 and the tilt close switch SW7 are connected respectively. The various switches SW2 to SW7 are the drive control circuit 11
Inside, it is connected to the control unit 13 via the input circuit 14. When each of the switches SW2 to SW7 is operated, it outputs a command signal (ON signal) to the control unit 13 via the input circuit 14.

A reference clock signal necessary for the operation of the control unit 13 is input to the control unit 13 from a clock transmission circuit 15. Further, in the control unit 13, the driving power supplied from the power supply circuit 12 is monitored by the voltage monitor circuit 16.

Further, the control section 13 supplies drive power to the drive motor 5 via the drive circuit 17 to supply the drive power to the drive motor 5.
Control. Specifically, the control unit 13 drives the drive motor 5 to normally open the roof glass 4 while operating the normal slide opening switch SW2, that is, while receiving the ON signal from the switch SW2. Drive power is supplied to drive the motor 5. On the other hand, the control unit 13 drives the drive motor 5 to normally close the roof glass 4 while operating the normal slide close switch SW3, that is, while the ON signal is being input from the switch SW3. Is supplied to drive the motor 5. The control unit 13 normally stops the operation of the slide opening / closing switches SW2 and SW3, that is, the switch SW.
2, when an OFF signal is input from SW3, the supply of drive power to the drive motor 5 is stopped in order to stop the operation of the roof glass 4.

Further, when the automatic slide opening switch SW4 is once operated, that is, an ON signal is once inputted from the switch SW4, the control section 13 thereafter causes the switch SW to be turned on.
Even if an OFF signal is input from the motor 4, the drive power is supplied to the drive motor 5 so that the roof glass 4 can be automatically opened from the fully closed position to the fully opened position.
To drive. Then, when it is detected that the roof glass 4 is placed at the fully open position by detecting the opening / closing position of the roof glass 4 described later, the control unit 13 drives the drive motor 5
The driving power supply to the roof glass 4 is stopped and the operation of the roof glass 4 is stopped. On the other hand, when the auto-slide closing switch SW5 is once operated, that is, an ON signal is once input from the switch SW5, the control unit 13 fully opens the roof glass 4 even if an OFF signal is subsequently input from the switch SW5. The drive power is supplied to the drive motor 5 to drive the motor 5 so as to perform the automatic closing operation in which the position is closed at once from the position to the fully closed position. Then, when it is detected that the roof glass 4 is placed at the fully closed position by detecting the opening / closing position of the roof glass 4 which will be described later, the control unit 13 stops the drive power supply to the drive motor 5 and the roof is closed. The operation of the glass 4 is stopped.

The control unit 13 also controls the tilt open switch SW.
While operating the switch 6, that is, while the ON signal is being input from the switch SW6, the drive power is supplied to the drive motor 5 to drive the roof glass 4 to tilt and open. On the other hand, the control unit 13 supplies drive power to the drive motor 5 to operate the tilt closing of the roof glass 4 while operating the tilt closing switch SW7, that is, while the ON signal is input from the switch SW7. Then, the motor 5 is driven. The control unit 13 stops the operation of the tilt opening / closing switches SW6 and SW7, that is, when an OFF signal is input from the switches SW6 and SW7, the drive motor 5 is operated to stop the operation of the roof glass 4.
To stop the drive power supply.

The drive control circuit 11 includes a drive motor 5
Hall element magnetic sensors 18a and 18b as a pair of rotation sensors for detecting the rotation cycle and rotation direction of the circuit 1
1 is provided on the substrate. Specifically, a multi-pole magnetized sensor magnet is provided on the rotation shaft (not shown) of the drive motor 5 so as to rotate integrally, and the Hall element magnetic sensor 18a, 18b are arranged at predetermined intervals in the rotational direction. That is, as the rotation sensor of this embodiment, a non-contact rotation sensor using magnetism is used. When the drive motor 5 rotates, each of the Hall element magnetic sensors 18a and 18b outputs a pulsed output signal corresponding to the rotation of the motor 5 to the detection circuit 19. or,
The output signals (pulse signals) output from the Hall element magnetic sensors 18a and 18b have a phase difference (for example, 1
/ 2 cycle). The detection circuit 19 shapes the waveform of each output signal (pulse signal) and outputs it to the control unit 13.

The control unit 13 drives the drive motor 5 based on the cycle of the output signal (pulse signal) input from the Hall element magnetic sensors 18a and 18b through the detection circuit 19.
The rotation cycle of is detected. Further, when the normal slide open switch SW2 and the automatic slide open switch SW4 are operated and the ON signal is input, the control unit 13 outputs the output signal (pulse signal) every cycle (for example, based on the rising edge). ) Add "1" to the count number. still,
The count number is set to "0" when the roof glass 4 is arranged at the fully closed position. On the other hand, when the normal slide close switch SW3 and the auto slide close switch SW5 are operated and the ON signal is input, the control unit 13 adds the count number added at the time of opening for each cycle of the output signal (pulse signal). "1" is subtracted from. Then, the control unit 13 is adapted to detect the opening / closing position of the roof glass 4 according to the count number.
The control unit 13 does not perform the counting operation when the roof glass 4 is tilted or opened. In addition, the control unit 13
The rotation direction of the drive motor 5 is detected according to the phase difference between the output signals (pulse signals), and the opening / closing direction of the roof glass 4 is detected based on the detection of the rotation direction of the drive motor 5.

Further, when the rotation cycle of the drive motor 5 becomes longer than a predetermined entrapment determination value while the roof glass 4 is performing the automatic closing operation, the control section 13 causes the roof glass 4 and the roof panel 2 to be closed. It is determined that the foreign matter is pinched between and and the rotation cycle becomes longer. Then, the control unit 13 reverses the drive motor 5 to release the foreign matter sandwiched by the roof glass 4 being closed, and opens the roof glass 4 by a predetermined count. At this time, the control unit 13 switches the count number from subtraction to addition based on the reverse rotation of the drive motor 5.

Further, the control unit 13 operates during the operation of the drive motor 5 for each cycle of the output signal (pulse signal) input from each Hall element magnetic sensor 18a, 18b through the detection circuit 19 (for example, Based on the rising edge), the abnormality determination processing of the output signal is executed according to the processing flow shown in FIG.

In step S1, the control unit 13 determines whether the output signal input from the Hall element magnetic sensors 18a and 18b via the detection circuit 19 is normal. In this case, when the drive motor 5 rotates, one output signal does not rise twice or more times a predetermined number of times in succession. Therefore, if the one output signal rises less than the predetermined number of times, the control unit 13 normally operates. It is determined to be abnormal if the abnormality continues for a predetermined number of times. If both output signals are normal, the output signal abnormality determination processing is terminated, and the drive motor 5 is normally operated based on the switches SW2 to SW7.

On the other hand, in the step S1, for example, the Hall element magnetic sensors 18a and 18b fail for some reason, and either or both output signals are at the power supply voltage level (H level) or the ground level (L level). If it is constant, that is, if it is abnormal, the control unit 13 proceeds to step S2.

In step S2, the control unit 13 determines whether or not the output signal has only one abnormality.
When there is only one abnormality in the output signal, the control unit 13
Go to step S3.

In step S3, the control unit 13 prohibits only the automatic slide closing operation of the roof glass 4.
That is, the control unit 13 controls the automatic slide closing switch S.
Even if W5 is operated and an ON signal is input from the switch SW5, power is not supplied to the drive motor 5. That is,
The control unit 13 invalidates the ON signal from the automatic slide closing switch SW5.

More specifically, when one of the output signals is abnormal, the rotation direction of the drive motor 5 is unknown, but the control unit 13 can perform the counting operation based on the other normal output signal. The open / close position of the roof glass 4 can be detected even when the normal slide opening / closing operation is performed. Similarly, in the automatic slide opening operation, the control unit 13 can detect the opening / closing position of the roof glass 4. On the other hand, at the time of the automatic slide closing operation, the drive motor 5 may rotate in the reverse direction due to the pinching. Therefore, the control unit 13 needs to switch the count operation from the subtraction to the addition at the time of the reverse rotation. Since the direction is unknown, the count number cannot be switched, and the gap between the opening / closing position of the roof glass 4 based on the count number and the actual opening / closing position of the roof glass 4 becomes large. Therefore, in this embodiment,
Only the automatic slide closing operation that may cause an error in the number of counts is prohibited to prevent the malfunction of the device, while the other operations (normal slide opening / closing operation and automatic slide closing operation) are permitted. There is.

That is, the sunroof device of this embodiment is
For example, one Hall element magnetic sensor 18a (, 18b)
If one of the output signals is abnormal, the open / close switch is operated to operate the roof glass 4 up to an arbitrary open / close position of the operator, such as a fully closed position or a fully open position, as in the conventional case. It is not necessary to operate the roof glass 4 repeatedly, and the slide glass switches SW2 and SW3 can be operated once to operate the roof glass 4 to any opening / closing position of the operator. Further, in this case, since the roof glass 4 does not perform the automatic slide closing operation even if the automatic slide closing switch SW5 is operated, the operator can easily recognize the failure of the sunroof device.

In the step S2, the control unit 1
3 indicates that if the output signal is both abnormal, the open / close position and the open / close direction of the roof glass 4 cannot be detected, and therefore the process proceeds to step S4. Prohibit automatic slide opening and closing. Also, normal slide open / close switches SW2, SW
3 is operated, the control unit 13 permits the drive motor 5 to be driven for a predetermined time, and the roof glass 4 can be opened and closed only during that time.

As described above, the sunroof device of this embodiment has the following features. (1) When one of the output signals from the Hall element magnetic sensors 18a and 18b that detects the rotation cycle and the rotation direction of the drive motor 5 is abnormal, the control unit 13 outputs a command signal from the automatic slide closing switch SW5. It is invalidated and the automatic slide closing operation of the roof glass 4 is prohibited. That is,
When an abnormality occurs in one of the output signals from the Hall element magnetic sensors 18a and 18b, the rotation direction of the drive motor 5 cannot be detected. Therefore, if pinching occurs during the automatic slide closing operation, the open / close switch SW
2 Since the drive motor 5 is driven in the reverse direction regardless of the operation of SW5, the opening / closing position of the roof glass 4 detected based on the output signals of the Hall element magnetic sensors 18a, 18b and the actual opening / closing position of the roof glass 4 are deviated. Becomes larger, which hinders subsequent opening and closing operations. Therefore, by prohibiting the automatic slide closing operation, malfunction of the sunroof device can be prevented in advance. Further, since the operation of the roof glass 4 by the normal slide opening / closing operation and the automatic slide opening operation can be continued, the normal slide opening / closing switches SW2 and SW3 and the automatic slide opening switch SW4
The roof glass 4 can be opened and closed to an arbitrary opening / closing position of the operator, such as a fully open position or a fully closed position, by a single operation of. Further, in this case, since the roof glass 4 does not perform the automatic slide closing operation even if the automatic slide closing switch SW5 is operated, the operator can easily recognize the failure of the sunroof device.

(2) Since the drive motor 5 and the drive control circuit 11 having the Hall element magnetic sensors 18a and 18b and the control unit 13 are integrally configured as the drive unit 10, the sunroof device can be easily assembled. can do.

The embodiment of the present invention may be modified as follows. In the above embodiment, it is determined that one output signal is normal if it rises less than the predetermined number of times and abnormal if the output signal continues abnormally for the predetermined number of times, but the abnormality determination is not limited to this.

In the above embodiment, when one output signal is abnormal, only the automatic slide closing operation is prohibited,
Although the operation of the roof glass 4 by the normal slide opening / closing operation and the automatic slide opening operation is continuously enabled, both the automatic slide opening / closing operation may be prohibited. That is, the operation of the roof glass 4 may be continuously enabled only by the normal slide opening / closing operation.

In the above embodiment, when the rotation cycle of the drive motor 5 becomes longer than a predetermined entrapment determination value, it is determined that entrapment has occurred by the roof glass 4, but the entrapment determination is not limited to this. Not something.

In the above embodiment, the Hall element magnetic sensors 18a and 18b are used as the rotation sensor, but a magnetoresistive element whose resistance changes with a change in magnetic field may be used.
In addition to the non-contact type magnetic sensor as described above, for example, an optical rotation sensor may be used. Alternatively, a contact type rotation sensor using a sliding contact may be used.

The circuit configuration of the drive control circuit 11 of the above embodiment is not limited to this, and may be changed appropriately. For example, the control unit 13 collectively performs the above-described various controls, but may have a configuration in which a plurality of control units are provided and shared and controlled by the respective control units.

In the above embodiment, the drive motor 5 and the drive control circuit 11 having the Hall element magnetic sensors 18a and 18b and the control unit 13 are integrally formed as the drive unit 10, but the present invention is not limited to this. Instead, for example, the drive control circuit 11 may be separately provided.

In the above embodiment, the sunroof device is used to perform both the slide opening / closing operation and the tilt opening / closing operation. However, the sunroof device may be used to perform only the slide opening / closing operation.

In the above embodiment, the sunroof device having the opening / closing member as the roof glass is used. However, other devices such as a power window device having the opening / closing member as a window glass, a sliding door device having the opening / closing member as a sliding door, etc. May be carried out.
